Blizzard Entertainment has posted new information on their upcoming massively multiplayer online RPG (MMORPG) World of Warcraft discussing the in-game banking system. Instead of storing your money though, the banks will be used to store items you might not have room to carry around with your all the time. Your money is instead kept with you and according to the page, "[it] has no weight and does not take up any inventory slots, so no matter how much you’re carrying, it will never have a negative effect on your character."

You will have many options to retrieve items from the game's bank and will even be able to upgrade your account to hold more items if necessary. Here's more from Blizzard on the topic:

You can also buy extra storage space at each bank, which provides you with slots for storing additional bags of items. The larger the bag that you put in each bag slot, the more space you'll have! For example, you might start with a 6-slot bag in one of your bag slots, but later on you might find a 10-slot bag to put there, which would essentially give you 4 more bank slots. The price for additional bag slots goes up with each new slot, and the final slots are very expensive!
